Abstract
The utility model provides a kind of undercarriage rocking arm, and one end of rocking arm is articulated with fuselage, other end connection wheel；Line slideway is set on the rocking arm, and the buffer end of undercarriage is arranged in the line slideway, and the other end of the buffer is articulated with fuselage.The rocking arm is cylindric, and the line slideway is the groove for being arranged at the rocking arm side.The both ends of the line slideway are semicircle.The end that the buffer is located in line slideway is spheroidal, and line slideway sets the limiting section being caught in buffer rounded ends in line slideway.The beneficial effects of the utility model are：The articulated structure between rocking arm and buffer is eliminated, avoids the failure caused by articulated structure damages, it is safer.
Description
Technical field
It the utility model is related to aviation helicopter, undercarriage technical field, and in particular to a kind of rocking arm of undercarriage.
Background technology
Undercarriage is that aircraft bottom is used to taking off landing or aircraft is supported during ground taxi and for the device of ground moving.
During aircraft landing, always with certain speed impacts ground, undercarriage bears and slows down this shock, so as to mitigate aircraft
Stand under load.Undercarriage is the important part with load and maneuverability of aircraft, is undertaken during aircraft security landing
Extremely important mission.Undercarriage it is excellent it is most important be embodied in its buffer capacity, the quality of its performance is directly connected to
Aircraft it is safe to use.Rocking arm and buffer are hinged by many landing gear structures in the prior art, and this structure uses for a long time
Junction bit loss will be caused bad, so as to produce failure.If undercarriage breaks down, aircraft hard landing, airframe structure will be caused
It is destroyed, or even there is fatal crass.
Utility model content
The utility model provides a kind of undercarriage rocking arm, has more excellent security performance.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical scheme that：
Undercarriage rocking arm, it is characterised in that one end of rocking arm is articulated with fuselage, other end connection wheel；It is described to shake
Line slideway is set on arm, the buffer end of undercarriage is arranged in the line slideway, the buffer it is another
End is articulated with fuselage.
Foregoing undercarriage rocking arm, it is characterised in that the rocking arm is cylindric, and the line slideway is to be arranged at
The groove of the rocking arm side.
Foregoing undercarriage rocking arm, it is characterised in that the both ends of the line slideway are semicircle.
Foregoing undercarriage rocking arm, it is characterised in that the end that the buffer is located in line slideway is ball
Shape, and line slideway sets the limiting section being caught in buffer rounded ends in line slideway.
Foregoing undercarriage rocking arm, it is characterised in that the line slideway upper end is set can be to line slideway inside
The oil nozzle of lubricating oil is added, the oil nozzle is connected with through hole with line slideway.
Foregoing undercarriage rocking arm, it is characterised in that the wheel of the end connection of rocking arm is Double-wheel structure.
The beneficial effects of the utility model are：The articulated structure between rocking arm and buffer is eliminated, is avoided because of be hinged knot
Failure caused by structure damage, it is safer.
Brief description of the drawings
The utility model is further described with reference to the accompanying drawings and detailed description：
Fig. 1 is top view of the present utility model；
Fig. 2 is the utility model rocking arm and the undercarriage schematic diagram formed after buffer, wheel assembling.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings：
Undercarriage rocking arm, it is characterised in that rocking arm（1）One end be articulated with fuselage, other end connection wheel（3）；
The rocking arm（1）Upper setting line slideway（11）, the buffer of undercarriage（2）End set is in the line slideway（11）
It is interior, the buffer（2）The other end be articulated with fuselage.
The rocking arm（1）To be cylindric, the line slideway（11）To be arranged at the rocking arm（1）The groove of side.Institute
State line slideway（11）Both ends for semicircle.The buffer（2）Positioned at line slideway（11）Interior end is spheroidal,
And line slideway（11）Set and buffer rounded ends are caught in line slideway（11）Interior limiting section（12）.
The line slideway（11）Upper end is set can be to line slideway（11）The oil nozzle of inside addition lubricating oil（13）, it is described
Oil nozzle（13）With line slideway（11）It is connected with through hole（14）.Rocking arm（1）End connection wheel（3）For Double-wheel structure.
During aircraft landing, undercarriage bears pressure, and buffer, which is pressurized, to be shortened, and buffer end is in the line slideway of rocking arm
Mobile, the undercarriage that the utility model is combined into eliminates the articulated structure between rocking arm and buffer, avoided because of articulated structure
Failure caused by damage.
In summary, rocking arm provided by the utility model is more safe and reliable.
Based on the embodiment in the utility model, those of ordinary skill in the art are not making the premise of creative work
Lower obtained every other embodiment, belong to the scope of the utility model protection.
